HENRY K. .GILBERT, OF CHICAGO, ILLINOIS.

ANTIOREEPER.

To all whom it may concern:

Be it known that I, HENRY K. GILBERT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements] in Anticreepers, of

.ing tie over an extended surface; and finally, to provide a device of inexpensive construction, of minimum weight and great simplicity. One form of the invention is shown in the accompanying drawings in which.'

Figure 1 isfa transverse section through a rail showing my creeper as applied thereto;

Figure 2 isan end view of the creeper looking from the right of Figure 1, and shows such creeper'in positionagainst the holding tie, and I Figure 3 is a section on the line IIIIII of Figure 1. Referring to the drawing, it will be seen that the deviceis composed of two clamping members, 1 and 2,

which members are provided with hooks 3 and 4 for engaging the flanges of the rail, and these members are on the member 1 has its sides inclined to each othe'r at an angle slightly more acute than the angle formed by the sides oi' th'e flange, whereby when the member is in the position shown in Figure l the hook 3 tightly clamps the flange of. the rail which clamping action is accentuated by theprovision of teeth 6 (Figure 3)-for engaging and biting int'othe uppersurface of the flange. In order to. strengthen the clamping member land also to secure an extended bearing surface of such member against the .tie 7, the rib 8 is provided, which rib is'preferably made in the -shape'shown in Figure 1. As clearly shownin Figure'l, the left hand end of the member-1 isprovided with the toothed surface 9 for engaging a corresponding surface on the i member 3, so that when the twoinembers are clamped together by the bo1t 5, the shearing strain on such bolt 5 is removed, due totheiriterlocking of the-teeth. An important feature of the invention resides inthe disposition of the hook 3 on themember 1. This hooked member 3, as above stated, is provided on its under face with transversely, extending teeth 6, and, as indicated in Figure 2, the hook is canted forwardly,

thus bringing the teeth on such hook'at a slight angle to the axis of the rail. If the tendency of the rail is Specification of Letters Patent. Application filed November 14,1906. Serial No. 343,330.

to creep in the direction of the arrow in Figure 2, it will be seen that such movement against the inclined teeth on the member 3 will tend to move such member toward the center of the rail, thus clamping the rail still more securely. It will be noted that the bolt 5 is upwardly inclined with respect to the horizontal, so that when the nut is tightened the members 1 and 2 will not only be moved laterally towards each other, but the member 4 will be moved downwardly, due to the component offorce in that directionybecans of the slant of the bolt. This gives a very effective clamping at theflange engaged by the hook '4.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following.

1. An anti-creeper for ralls comprising a clamping mem I her adapted to engage one flange of the rail and extend across the bottom of the rail, and a second. clamping meniber adapted to engage-the other flange of the ruif and abut against the end of the first member, together with means for securing the members together.

2. An anti-creeper for rails comprising transverse clamping members engaging therail flange, one of which memhers is provided with transverse teeth and is canted in the direction of the tendency of the rail to creep. p

3. An antl creeper for rails comprising transverse clamplug members engaging the rail flange, which members are provided with transverse teeth and one of whichJnembers ls canted in the direction of the tendency of the rail to creep. v

4. An antl-creeper for rails comprising, a clamping member adapted to engage onefiange of the'r'ail'and provided with a flange portion extending across the bottom of the rail, and a second clamping member adapted to engage the other flange of the rail and abut against the end of the first member, together with means for-securing the memhers together.

i 5. An anti-creeper for rails comprising a clamping member adapted to engage one flange of the rail and provided with a toothed portion extending across and downwardly '.below the rail, and a second clamping member adapted to engage the other flangeof the rall'nnd provided .with a toothed portion for engaging the teeth on the first member.

together with. bolt for holding the toothed surfaces together.

6. An anti-creeper for rails-comprising a clamping member adapted to engage one flange of the rail and provided with a-to'othed portion extending 'across and-downwardly below the rail, and a second clumpingmember adapted to engage the other flange of the rail and provided with :1 toothed portion for engaging the teeth of the first member,

together with a bolt upwardly tilted from the horizontal for drawing the second clamping member against the rail fiange and for holding the toothed surfaces together.

In testimony whereof I have hereunto signed my name in the presence of the .two subscribed witnesses.
